Remote for the brain
It doesn't seem real, but scientists at Arizona State University have developed a remote control for the brain. In the course of numerous experiments and studies, scientists have found that ultrasound with a relatively low frequency and intensity allows you to change the behavior of neural circuits and the reaction rate between them.
Previously, such effects on the brain required the direct use of electrodes and were used in the treatment of drug addiction and depression. Ultrasonic technique allows avoiding contact with the patient’s skull, which is critical in the treatment of unbalanced patients.
However, the researchers do not intend to stop only on the medical component of the technology. In the future, such devices can be used in many fields of science and technology, including video games and the generation of artificial dreams.
